Granted: 1990-12-27
Abstract: PROCESSOR ACCESS CONTROL ARRANGEMENT      IN A MULTIPROCESSOR SYSTEM     Abstract In a multiprocessor system, processors are connected to an interconnecting bus by means of bus interface circuits which comprise an address buffer in addition to data buffers.  The interconnecting bus, in addition to a destination address and data also carries an originating address identifying the processor transmitting the data.  In the event of a receive buffer overload condition in the receiving bus interface circuit, a negative acknowledge signal is transmitted on the bus and the originating address is queued in the address buffer.  When the buffer overflow condition has been relieved, a retransmission request is sent to the first processor identified in the address buffer and its message is received.  This procedure will be repeated for each processor identified in the address buffer.

Title: Method and apparatus for simulating systems described by partial differential equations
Inventor: WOLFRAM STEPHEN
IPC: B64F5/00
Filed: 1986-12-29
Granted: 1990-06-19
Abstract: ABSTRACT A METHOD AND APPARATUS FOR SIMULATING SYSTEMS DESCRIBED BY PARTIAL DIFFERENTIAL EQUATIONS A method and apparatus are disclosed for using cellular automata to simulate systems described by partial differential equations such as those that describe the flow of fluid, diffusion or heat transfer. A two-dimensional space is tessellated into a cellular array of regular hexagons. Flow or diffusion into a cell through each of its six sides from each of its six nearest neighbor cells is represented by a value 1; and any other condition is represented by a value 0. A set of rules specifies the effect of such inward flow in terms of an outward flow through at least some of the same six sides of each cell to its nearest neighbors. Interaction of the flow with a surface or other inhomogeneity is simulated by using a different set of rules to specify the outward flow produced when an inward flow encounters a surface or other inhomogeneity in the cell. Outward flow from one cell is an inward flow into its nearest neighbors; and with the next "tick" of the clock of the model, the cycle repeats itself. Over long periods of time such as tens of thousands of ticks of the clock, this process has been shown to simulate the flow of a real fluid an inclined straight-edge.

Abstract: COLOR BURST REGENERATION            ABSTRACT OF THE DISCLOSURE A system for regenerating a standard-length color burst signal from a less-than-standard-length color burst information signal of a given frequency and phase. The system includes a phase-locked loop for generating a system clock signal from the color burst information signal, with the clock signal having a clock frequency related to and at least twice the given frequency of the color burst information signal The phase information from the color burst information signal is sampled and stored in a RAM. The sampling is clocked by the system clock signal. A standard-length color burst signal is regenerated at the given frequency and in phase with the color burst information signal by retrieving the stored phase information and extrapolating the standard-length signal in accordance with the retrieved phase information. Such retrieval is clocked by the system signal. The phase-locked loop is a digital phase locked loop; and the color burst information signal is converted into a digital color burst information signal for processing by the phase-locked loop and for sampling and retrieval of the phase information. Upon retrieval and extrapolation of the phase information samples, the retrieved and extrapolated phase information samples arc converted into an analog sample information signal. which is converted into a regenerated sinusoidal standard-length color burst signal by a low pass filter.

Granted: 1991-05-14
Abstract: ABSTRACT OF THE DISCLOSURE A liquid crystal display unit has a video signal receiver and a first store for storing video signals. Time-modulation grey-scale addressing of the ferroelectric liquid crystal pixels in a display panel is provided to a change-of-state store which records the number of changes of state for each pixel during one picture-signal. Once the most-significent bit has been processed and is being displayed on the panel, the change-of-state store has the net number of changes which the pixel has undergone in that picture. A controller causes the change-of-state store to output the value appropriate to that pixel and pass it to a pixel driver unit to produce a compensating pulse (whether positive, negative or zero) necessary to ensure that there is no net electrical potential over the entire picture interval. The display produced by the compensating pulse is cleared immediately the first data of the next picture is input to the pixel. Assuming that the LSB of the data for a pixel is already on display in the display panel, then in the next scan, a bit extractor passes the next LSB to a comparator whose other input is connected to a pixel-state store. Accordingly, the new bit-value is compared with the existing state of the pixel, and the comparator passes on an instructing signal to the pixel driver unit only if the state of the pixel requires changing; in such an eventuality, the pixel driver unit issues an appropriate monopulse select voltage. The comparator also passes such an instructing signal.

Abstract: ABSTRACT OF THE DISCLOSURE An improved control system for selectively clamping a die to a power press or similar machine by means of a plurality of hydraulically actuated clamps.  Such hydraulically actuated clamps are provided for securing the opposed halves of the die to the bolster and ram of the press.  The clamps are connected in alternating fashion to first and second fluid conduits for both the bolster and the the ram.  Each of the conduits is connected to a source of pressurized fluid.  The first and second conduits on the bolster and the ram provide a safety redundancy feature in case one of the conduits on the bolster or the ram fails. Each of the conduits is provided with first and second pressure sensors.  The first pressure sensors are each adapted to generate an electrical output signal when the pressure in the associated conduit falls below a first predetermined level.  The second pressure sensors are each adapted to generate an electrical output signal when the pressure in the associated conduit falls below a second predetermined level, the second predetermined pressure level being less than the first predetermined pressure level.  A microprocessor monitors the output signals from each of the pressure sensors and regulates the operation of the source of pressurized fluid, as well as the operation of the press itself, in response thereto.  A snugging feature is included in the control system for causing the ram clamps to loosely engage one of the opposed die halves during the initial setup of the press.  In this manner, the die halves can be positioned precisely relative to one another before beginning normal operation of the press.
